Rheological testing with the Kinexus DSR Series

ASPHALT BINDER AND BITUMENCharacterization and classification to asphalt industry standards

Asphalt, or bitumen, is a petroleum product used in the road (pavement), roofing and construction industries. A mixture of aromatic hydrocarbons (varying with geographical source), this black viscoelastic material is considered to be a complex colloidal system.

Asphalt is used as a binder with aggregates in road (pavement) construction and as such determines performance and lifetime. Additives such as polymers, crumb rubber, oils, waxes, phosphates and pH adjusters are used to enhance mechanical properties in modified asphalt binders. Asphalt emulsions are also used as water-proofing and re-surfacing materials.

Rheological characterization by Dynamic Shear Rheometers (DSR) is the standard method of classifying asphalt binders for behavior over time and loading conditions, and in different climates.

While some still use viscosity (vis) and penetration (pen) methods for grading, the use of DSR grading methods provides a much broader range of information about the asphalt performance properties and its suitability for desired applications. This is especially the case with engineered binders; binders designed with elastomeric properties to reduce rutting, aging, thermal and fatigue cracking.

• Grade testing to industry standards such as AASHTO , ASTM and EN specifications (see www.malvern.com/kinexus for a full list)

• Full characterization of rheological behavior with Master Curves

UNPRECEDENTED DUAL-ACTION CAPABILITIESA revolution in shear and vertical (axial) test control

The unique combination of Kinexus DSR hardware technology and rSpace software gives the user the ability to configure three critical rheometer functions independently:

• Rotational (shear) control - torque, speed and position

• Vertical (axial) control – gap and Normal Force

• Temperature control

Offering the ultimate in rheological test flexibility for both industry and academia, Kinexus DSR enables:

• All rotational shear-based testing

• Advanced vertical (axial) testing including pull-off, squeeze flow and tack testing

• A combination of shear and vertical actions for revolutionary process-relevant measurements

Kinexus DSR combines high speed and ultra-fine resolution gap control with high sensitivity and ultra-responsive Normal Force control for truly innovative sample loading and measurement capabilities – from sensitive structures to rapid curing systems.

Allied to ‘cradle to grave’ data collection providing a complete sample history from loading to unloading, every aspect of rheological testing can be optimized and verified for total consistency.

Significant design effort has been directed at the vertical, or axial capabilities of the Kinexus DSR platform – an area that typically sees compromises on most rheometer systems.

rSpace - Powerful, user friendly, flexible and easily tailored

rSpace software is driven by ‘sequences’ – which consist of fundamental rheological actions (or test building blocks) that can be linked together with other test actions, such as user feedback and choices, calculate values, loops and triggers, in order to build ‘intelligent’ tests.

• Set a sequence to ‘run’ only, and a user operates under SOP-type conditions with defined test instructions and feedback

• Set user access to ‘edit’ sequence functionality, and researchers have the full design capabilities at their fingertips

‘What rheological test progression would you like to run?’

• You think it - Kinexus can run it

• Dedicated and advanced tests exactly to your needs

Program sequence in Kinexus
